Expose n-gram analyzer

[natcohen]

I'd love to contribute to expose the n-gram analyzer but I don't know where to start!

Anyone can help? There is no documentation about contribution

@rnewson Any chance someone can give a little help here?

My personal focus is on the successor project to dreyfus/clouseau that targets the future CouchDB 4.0 (with the FoundationDB backend) but I can review a pull request.

The https://github.com/cloudant-labs/clouseau/blob/master/src/main/scala/com/cloudant/clouseau/SupportedAnalyzers.scala should be the only place that needs working on to add a new analyzer, though you may need to think about how to add extra configuration parameters. (the number of characters per ngram being the obvious one).

@rnewson I m excited for the 4th version of CouchDB but that would be great if you could help me with that...

Here are my two attempts for ngram and edgengram:

NGram: #30
EdgeNGram: #31
